151 Heterojunction bipolar transistor sigma-delta analog to digital converter for spread spectrum receiverThe focus of this thesis work was to investigate a means of implementing a high speed sigma-delta modulator that can be used as the front end of a direct sequence spread spectrum receiver.sigma-delta modulator; computers1995-12
152 High-speed conterflow-clocked pipelining illustrated on the design of subband vector quantizatizer chipsThis dissertation introduces Counterflow-Clocked (C2) pipelining and discusses its usefulness and limitations to build large, high speed VLSI chips. It also presents the design of an image compression chip set to implement subband vector quantization that can handle HDTV data rates with reasonable V...VLSI chips; counterflow-clocked pipelining; computers1995-12
153 Localization in outdoor static terrain (LOST)This thesis considers problems that arise while combining these strategies with a feature based approach to the localization problem. A subset of strategies were simplified and implemented, along with key feature based concepts. This experimentation has helped to point out and clarify some aspects o...localization problem; LOST; localization; computers1995-12
154 Graph-based approach for solving geometric constraint problemsThis dissertation presents a new graph representation for constraint problems based on the notion of degrees of freedom and valencies. Any geometric primitive ( point, line, circle, plane, etc.) possess an intrinsic degree of freedom in its embedding space. Constraints reduce the degrees of freedom ...computers; geometric constraint problems; graph1996-05
155 Shape recovery of volume data with deformable B-spline modelsThe research described in this dissertation explores a new technique for shape recovery with deformable models using B-spline surfaces.b-spline surfaces; computers1996-08
156 Scientific visualization for finite element analysis data setsThe research is focused on developing new techniques for visualizing FEA data sets. In this thesis, new parallel volume rendering algorithms are outlined to speed up scalar field visualization. Strreamlines, streamribbons and streamtubes are the most fundamental tools for exploring vector field data...finite element analysis; FEA; computers; algorithms1996-08
157 TWEAK: A three-dimensional toolkit and modeling system using snapping and constraintsThe goal of this thesis is to provide a simple and intuitive user interface to a three-dimensional (3D) Computer Aided Design system. The interactive modeling system described here was built to demonstrate the utility of this user interface. The four main parts of the system are discussed.Tweak; snapping; constraint; interactive modeling system; DI-3D graphics library1996-12
158 Extraction of Micro-Terrain FeaturesMicro-terrain features are topographic structures relavent to the behavior of a simulation, but with a horizontal extent significantly less than the resolution of the base-level terrain data covering the area in which these structures occur. Thus, these features are not directly extractable from ele...1998-08
159 The Fluke Security ProjectThis document presents the final report of the University of Utah-based project officially titled ""Mach 4 Kernel and IDL Infrastructure for Security"" but often referred to as the ""Fluke Security"" Project. This project is noteworthy for the number diversity, scale, robustness, and documentation o...2000-04
160 A Java-based active network operating system (JANOS)The JANOS prqjects' primary objective was to develop a principle local operating system for active network nodes. The operating system is oriented toward executing untrusted Java bytecode, primarily for management and control.,The original document contains color images.2003-11
